Final manual curation in preparation for global clang-formating (#3712)
* Manual line breaks to pre-empt undesired `clang-format`ing.

Informed by work under https://github.com/pybind/pybind11/pull/3683:

60b7eb410f

59572e6559

* Manual curation of clang-format diffs involving source code comments.

Very labor-intensive and dull.

* Pulling .clang-format change from @henryiii's 9057962d40

* Adding commonly used .clang-format `CommentPragmas:`

* Ensure short lambdas are allowed

Fix smart_holder multiple inheritance tests (#3635)
The original pybind11 holder supported multiple inheritance by recursively creating
type casters until it finds one for the source type, then converting each
value in turn to the next type via typeinfo->implicit_cast

The smart_holder only stored the last implicit_cast, which was incorrect.

This commit changes it to create a list of implicit_cast functions that are
appended to during the recursive type caster creation, and when the time comes
to cast to the destination type, it calls all of them in the correct order.

Expand std::string_view support to str, bytes, memoryview (#3521)
* Expand string_view support to str, bytes, memoryview

1. Allows constructing a str or bytes implicitly from a string_view;
   this is essentially a small shortcut allowing a caller to write
   `py::bytes{sv}` rather than `py::bytes{sv.data(), sv.size()}`.

2. Allows implicit conversion *to* string_view from py::bytes -- this
   saves a fair bit more as currently there is no simple way to get such
   a view of the bytes without copying it (or resorting to Python API
   calls).

   (This is not done for `str` because when the str contains unicode we
   have to allocate to a temporary and so there might not be some string
   data we can properly view without owning.)

3. Allows `memoryview::from_memory` to accept a string_view.  As with
   the other from_memory calls, it's entirely your responsibility to
   keep it alive.

This also required moving the string_view availability detection into
detail/common.h because this PR needs it in pytypes.h, which is higher
up the include chain than cast.h where it was being detected currently.

* Move string_view include to pytypes.h

* CI-testing a fix for the "ambiguous conversion" issue.

This change is known to fix the `tensorflow::tstring` issue reported under https://github.com/pybind/pybind11/pull/3521#issuecomment-985100965

TODO: Minimal reproducer for the `tensorflow::tstring` issue.

Fix py::kw_only when used before the first arg of a method (#3488)
* Fix py::kw_only when used before the first arg of a method

The implicit space for the `self` argument isn't added until we hit the
first argument, but this wasn't being done for kw_only or pos_only, and
so a kw_only before the first argument would break.

This fixes it by properly checking whether we need to add the self arg.

(The pos_only issue here was extremely mild -- you didn't get the `/` in
the docstring, but AFAICT it has no other effect since there are no
meaningful arguments before it anyway).

* Style changes

- rename check_have_self_arg -> append_self_arg_if_needed

- move the argument name inline comments before the args instead of
  after

[master] Wrong caching of overrides (#3465)
* override: Fix wrong caching of the overrides

There was a problem when the python type, which was stored in override
cache for C++ functions, was destroyed and  the record wasn't removed from the
override cache. Therefor, dangling pointer was stored there. Then when the
memory was reused and new type was allocated at the given address and the
method with the same name (as previously stored in the cache) was actually
overridden in python, it would wrongly find it in the override cache for C++
functions and therefor override from python wouldn't be called.
The fix is to erase the type from the override cache when the type is destroyed.

* test: Pass by const ref instead of by value (clang-tidy)

* test: Rename classes and move to different files

Rename the classes and files so they're no too generic. Also, better place to
test the stuff is in test_virtual_functions.cpp/.py as we're basically testing
the virtual functions/trampolines.

* Add TODO for erasure code

feat: allow kw-only args after a py::args (#3402)
* Simply has_kw_only_args handling

This simplifies tracking the number of kw-only args by instead tracking
the number of positional arguments (which is really what we care about
everywhere this is used).

* Allow keyword-only arguments to follow py::args

This removes the constraint that py::args has to be last (or
second-last, with py::kwargs) and instead makes py::args imply
py::kw_only for any remaining arguments, allowing you to bind a function
that works the same way as a Python function such as:

    def f(a, *args, b):
        return a * b + sum(args)

    f(10, 1, 2, 3, b=20)  # == 206

With this change, you can bind such a function using:

    m.def("f", [](int a, py::args args, int b) { /* ... */ },
        "a"_a, "b"_a);

Or, to be more explicit about the keyword-only arguments:

    m.def("g", [](int a, py::args args, int b) { /* ... */ },
        "a"_a, py::kw_only{}, "b"_a);

(The only difference between the two is that the latter will fail at
binding time if the `kw_only{}` doesn't match the `py::args` position).

This doesn't affect backwards compatibility at all because, currently,
you can't have a py::args anywhere except the end/2nd-last.

* Take args/kwargs by const lvalue ref

fix: the types for return_value_policy_override in optional_caster (#3376)
* fix: the types for return_value_policy_override in optional_caster

`return_value_policy_override` was not being applied correctly in
`optional_caster` in two ways:
- The `is_lvalue_reference` condition referenced `T`, which was the
`optional<T>` type parameter from the class, when it should have used `T_`,
which was the parameter to the `cast` function. `T_` can potentially be a
reference type, but `T` will never be.
- The type parameter passed to `return_value_policy_override` should be
`T::value_type`, not `T`. This matches the way that the other STL container
type casters work.

The result of these issues was that a method/property definition which used a
`reference` or `reference_internal` return value policy would create a Python
value that's bound by reference to a temporary C++ object, resulting in
undefined behavior. For reasons that I was not able to figure out fully, it
seems like this causes problems when using old versions of `boost::optional`,
but not with recent versions of `boost::optional` or the `libstdc++`
implementation of `std::optional`. The issue (that the override to
`return_value_policy::move` is never being applied) is present for all
implementations, it just seems like that somehow doesn't result in problems for
the some implementation of `optional`. This change includes a regression type
with a custom optional-like type which was able to reproduce the issue.

Part of the issue with using the wrong types may have stemmed from the type
variables `T` and `T_` having very similar names. This also changes the type
variables in `optional_caster` to use slightly more descriptive names, which
also more closely follow the naming convention used by the other STL casters.

Fix make_key_iterator/make_value_iterator for prvalue iterators (#3348)
* Add a test showing a flaw in make_key_iterator/make_value_iterator

If the iterator dereference operator returns a value rather than a
reference (and that pair also does not *contain* references),
make_key_iterator and make_value_iterator will return a reference to a
temporary, causing a segfault.

* Fix make_key_iterator/make_value_iterator for prvalue iterators

If an iterator returns a pair<T1, T2> rather than a reference to a pair
or a pair of references, make_key_iterator and make_value_iterator would
return a reference to a temporary, typically leading to a segfault. This
is because the value category of member access to a prvalue is an
xvalue, not a prvalue, so decltype produces an rvalue reference type.
Fix the type calculation to handle this case.

I also removed some decltype parentheses that weren't needed, either
because the expression isn't one of the special cases for decltype or
because decltype was only used for SFINAE. Hopefully that makes the code
a bit more readable.

Closes #3347

feat: add .keys and .values to bind_map (#3310)
* Add `.keys` and `.values` to bind_map

Both of these implement views (rather than just iterators), and `.items`
is also upgraded to a view. In practical terms, this allows a view to be
iterated multiple times and have its size taken, neither of which works
with an iterator.

The views implement `__len__`, `__iter__`, and the keys view implements
`__contains__`. Testing membership also works in item and value views
because Python falls back to iteration. This won't be optimal
for item values since it's linear rather than O(log n) or O(1), but I
didn't fancy trying to get all the corner cases to match Python
behaviour (tuple of wrong types, wrong length tuple, not a tuple etc).

Missing relative to Python dictionary views is `__reversed__` (only
added to Python in 3.8). Implementing that could break code that binds
custom map classes which don't provide `rbegin`/`rend` (at least without
doing clever things with SFINAE), so I've not tried.

The size increase on my system is 131072 bytes, which is rather large
(5%) but also suspiciously round (2^17) and makes me suspect some
quantisation effect.

* bind_map: support any object in __contains__

Add extra overload of `__contains__` (for both the map itself and
KeysView) which takes an arbitrary object and returns false.

* Take py::object by const reference in __contains__

To keep clang-tidy happy.

* Removing stray `py::` (detected via interactive testing in Google environment).

feat: reapply fixed version of #3271 (#3293)
* Add make_value_iterator (#3271)

* Add make_value_iterator

This is the counterpart to make_key_iterator, and will allow
implementing a `value` method in `bind_map` (although doing so is left
for a subsequent PR).

I made a few design changes to reduce copy-and-paste boilerplate.
Previously detail::iterator_state had a boolean template parameter to
indicate whether it was being used for make_iterator or
make_key_iterator. I replaced the boolean with a class that determines
how to dereference the iterator. This allows for a generic
implementation of `__next__`.

I also added the ValueType and Extra... parameters to the iterator_state
template args, because I think it was a bug that they were missing: if
make_iterator is called twice with different values of these, only the
first set has effect (because the state class is only registered once).
There is still a potential issue in that the *values* of the extra
arguments are latched on the first call, but since most policies are
empty classes this should be even less common.

* Add some remove_cv_t to appease clang-tidy

* Make iterator_access and friends take reference

For some reason I'd accidentally made it take a const value, which
caused some issues with third-party packages.

* Another attempt to remove remove_cv_t from iterators

Some of the return types were const (non-reference) types because of the
pecularities of decltype: `decltype((*it).first)` is the *declared* type
of the member of the pair, rather than the type of the expression. So if
the reference type of the iterator is `pair<const int, int> &`, then the
decltype is `const int`. Wrapping an extra set of parentheses to form
`decltype(((*it).first))` would instead give `const int &`.

This means that the existing make_key_iterator actually returns by value
from `__next__`, rather than by reference. Since for mapping types, keys
are always const, this probably hasn't been noticed, but it will affect
make_value_iterator if the Python code tries to mutate the returned
objects. I've changed things to use double parentheses so that
make_iterator, make_key_iterator and make_value_iterator should now all
return the reference type of the iterator. I'll still need to add a test
for that; for now I'm just checking whether I can keep Clang-Tidy happy.

* Add back some NOLINTNEXTLINE to appease Clang-Tidy

This is favoured over using remove_cv_t because in some cases a const
value return type is deliberate (particularly for Eigen).

* Add a unit test for iterator referencing

Ensure that make_iterator, make_key_iterator and make_value_iterator
return references to the container elements, rather than copies. The
test for make_key_iterator fails to compile on master, which gives me
confidence that this branch has fixed it.

* Make the iterator_access etc operator() const

I'm actually a little surprised it compiled at all given that the
operator() is called on a temporary, but I don't claim to fully
understand all the different value types in C++11.

* Attempt to work around compiler bugs

https://godbolt.org/ shows an example where ICC gets the wrong result
for a decltype used as the default for a template argument, and CI also
showed problems with PGI. This is a shot in the dark to see if it fixes
things.

* Make a test constructor explicit (Clang-Tidy)

* Fix unit test on GCC 4.8.5

It seems to require the arguments to the std::pair constructor to be
implicitly convertible to the types in the pair, rather than just
requiring is_constructible.

* Remove DOXYGEN_SHOULD_SKIP_THIS guards

Now that a complex decltype expression has been replaced by a simpler
nested type, I'm hoping Doxygen will be able to build it without issues.

* Add comment to explain iterator_state template params

* fix: regression in #3271

Eliminate duplicate TLS keys for loader_life_support stack (#3275)

This revises the existing fix for
https://github.com/pybind/pybind11/issues/2765 in
https://github.com/pybind/pybind11/pull/3237 to reduce the amount of
TLS storage used.

The shared TLS key is stored in two different ways, depending on
`PYBIND11_INTERNALS_VERSION`.  If `PYBIND11_INTERNALS_VERSION ==
4` (as is currently set), the TLS key is stored in the
`internal::shared_data` map to avoid breaking ABI compatibility.  If
`PYBIND11_INTERNALS_VERSION > 4`, the TLS key is stored directly in
the `internals` struct.

Fix thread safety for pybind11 loader_life_support (#3237)
* Fix thread safety for pybind11 loader_life_support

Fixes issue: https://github.com/pybind/pybind11/issues/2765

This converts the vector of PyObjects to either a single void* or
a per-thread void* depending on the WITH_THREAD define.

The new field is used by each thread to construct a stack
of loader_life_support frames that can extend the life of python
objects.

The pointer is updated when the loader_life_support object is allocated
(which happens before a call) as well as on release.

Each loader_life_support maintains a set of PyObject references
that need to be lifetime extended; this is done by storing them
in a c++ std::unordered_set and clearing the references when the
method completes.

* Also update the internals version as the internal struct is no longer compatible

* Add test demonstrating threading works correctly.

It may be appropriate to run this under msan/tsan/etc.

* [pre-commit.ci] auto fixes from pre-commit.com hooks

* Removing safe_ssize_t.cpp (proof-of-concept code) to not upset the GHA Format workflow.

* Completing changes in pytypes.h

* New ssize_t_cast (better replacement for safe_ssize_t).

* clang-format-diff (no manual changes).

* bytes_ssize_t -Wnarrowing reproducer (see PR #2692).

* Backing out tuple(), list() ssize_t support, for compatibility with older compilers (to resolve link failures).

* Bug fix: missing `py::` for `py::ssize_t`

* Restoring tuple(), list() ssize_t support, but passing `size` by value, for compatibility with older compilers (to resolve link failures).

* Full test coverage of all functions with modified signatures.

Call PySys_SetArgv when initializing interpreter. (#2341)
* Call PySys_SetArgv when initializing interpreter.

* Document argc/argv parameters in initialize_interpreter.

* Remove manual memory management from set_interpreter_argv in favor of smart pointers.

* Use size_t for indexers in set_interpreter_argv.

* Minimize macros for flow control in set_interpreter_argv.

* Fix 'unused variable' warning on Py2

* whitespace

* Define wide_char_arg_deleter outside set_interpreter_argv.

* Do sys.path workaround in C++ rather than eval.

* Factor out wchar conversion to a separate function.

* Restore widened_argv variable declaration.

* Fix undeclared widened_arg variable on some paths.

* Use delete[] to match new wchar_t[].

* Fix compiler errors

* Use PY_VERSION_HEX for a cleaner CVE-2008-5983 mode check.

* Fix typo

* Use explicit type for deleter so delete[] works cross-compiler.

* Always use PySys_SetArgvEx because pybind11 doesn't support pythons that don't include it.

* Remove pointless ternary operator.

* Use unique_ptr.reset instead of a second initialization.

* Rename add_program_dir_to_path parameter to clarify intent.

* Add defined() check before evaluating HAVE_BROKEN_MBSTOWCS.

* Apply clang-tidy fixes

* Pre-commit

* refactor: use const for set_interpreter_argv

* Try to fix const issue and allocate vector properly

* fix: copy strings on Python 2

* Applying clang-format-diff relative to master.

The only manual change is an added empty line between pybind11 and system `#include`s.

Cleanup of file-scoped and globally-scoped warning suppression pragmas across pybind11 header files. (#3201)
* Removing all MSVC C4127 warning suppression pragmas.

* Removing MSVC /WX (WERROR). To get a full list of all warnings.

* Inserting PYBIND11_SILENCE_MSVC_C4127. Changing one runtime if to #if.

* Changing PYBIND11_SILENCE_MSVC_C4127 macro to use absolute namespace (for use outside pybind11 include directory).

* Restoring MSVC /WX (WERROR).

* Removing globally-scoped suppression for clang -Wunsequenced. Based on an experiment under PR #3202 it is obsolete and can simply be removed.

* Removing all pragma from eigen.h

* Removing -Werror or equivalent from tests/CMakeLists.txt

* Restoring tests/CMakeLists.txt from master.

* Adding 4 PYBIND11_SILENCE_MSVC_C4127.

* Compatibility with -Wconversion, -Wdeprecated

* Introducing PYBIND11_COMPATIBILITY_WDEPRECATED_COPY

* Systematically using --verbose for compilations where possible (cmake 3.14 or newer).

Also changing all `cmake -t` to `--target`, `-v` to `--verbose`, `check` to `pytest`, for consistency (to make it easier to pin-point all commands of a certain type).

Also removing one `-j 2` for `pytest` in hopes of reducing flakes due to races in test_iostream and in prints from destructors.

* Commenting out pragmas as an experiment to reproduce previous observation.

* Removing all (newly added, but already commented-out) pragma code, adding HINT use -isystem (as cmake does).

* Restoring ci.yml from master. Those changes are better handled separately. BTW: in the last CI run there was still a test_iostream flake, even without the -j 2 for running the tests (verfied by inspecting the log).

* Disabling -Werror for GNU (experiment).

* Commenting out the entire `if(PYBIND11_WERROR)` again (although that is not expected to make a difference, but who knows what I am overlooking).

* Adding `-DCMAKE_BUILD_TYPE=Release`

Removing GCC -Wunused-but-set-parameter from pragma block at the top of pybind11.h (#3164)
* Cleanup triggered by work on pragma for GCC -Wunused-but-set-parameter.

* Backing out changes to eigen.h (to be worked on later).

* Adding PYBIND11_WORKAROUND_INCORRECT_GCC_UNUSED_BUT_SET_PARAMETER in type_caster_base.h (apparently needed only for older GCCs).

* Apparently older compilers need a simpler overload for silence_unused_warnings().

* clang C++11 compatibility: removing constexpr

* Special case for MSVC 2017: `constexpr void` return

* Trying again without the silence_unused_warnings(const int *) overload.

* Separate macros for ALL_GCC, OLD_GCC_UNUSED_BUT_SET_PARAMETER

* Changing to __GNUC__ <= 2 (turning off)

* Refined condition for PYBIND11_WORKAROUND_INCORRECT_OLD_GCC_UNUSED_BUT_SET_PARAMETER.

* Quick experiment trying out suggestion by @henryiii

* Introducing macro: PYBIND11_INT_ARRAY_WORKING_AROUND_MSVC_CLANG_ISSUES

* Trying henryiii@ (void) expander idea.

* fix: apply simpler expression with fewer workarounds

* Purging new-but-already-obsoleted  macro, made possible by @henryiii's commit.

* Renaming `ALL_GCC` macro back to just `GCC` (because there is no `OLD` anymore, luckily).

* [actions skip] Adding "All GCC versions" to comment, to be clear about it.

Feature/local exception translator (#2650)
* Create a module_internals struct

Since we now have two things that are going to be module local, it felt
correct to add a struct to manage them.

* Add local exception translators

These are added via the  register_local_exception_translator function
and are then applied before the global translators

* Add unit tests to show the local exception translator works

* Fix a bug in the unit test with the string value of KeyError

* Fix a formatting issue

* Rename registered_local_types_cpp()

Rename it to get_registered_local_types_cpp() to disambiguate from the
new member of module_internals

* Add additional comments to new local exception code path

* Add a register_local_exception function

* Add additional unit tests for register_local_exception

* Use get_local_internals like get_internals

* Update documentation for new local exception feature

* Add back a missing space

* Clean-up some issues in the docs

* Remove the code duplication when translating exceptions

Separated out the exception processing into a standalone function in the
details namespace.

Clean-up some comments as per PR notes as well

* Remove the code duplication in register_exception

* Cleanup some formatting things caught by clang-format

* Remove the templates from exception translators

But I added a using declaration to alias the type.

* Remove the extra local from local_internals variable names

* Add an extra explanatory comment to local_internals

* Fix a typo in the code

* Splitting out pybind11/stl/filesystem.h.

To solve breakages like: https://github.com/deepmind/open_spiel/runs/2999582108

Mostly following the suggestion here: https://github.com/pybind/pybind11/pull/2730#issuecomment-750507575

Except using pybind11/stl/filesystem.h instead of pybind11/stlfs.h, as decided via chat.

stl.h restored to the exact state before merging PR #2730 via:
```
git checkout 733f8de24f stl.h
```

* Properly including new stl subdirectory in pip wheel config.

This now passes interactively:
```
pytest tests/extra_python_package/
```

* iwyu cleanup.

48eb78ae77 Simpler and safe implementation based on new requirement: C++ (outside of the Python object) needs to hold a shared_ptr before shared_from_this is called.

bf8d6a2900 First fully successful attempt to make shared_from_this and trampolines play nicely.
Now also passes the open_spiel iterated_prisoners_dilemma_test ASAN clean, in addition to all pybind11 and PyCLIF unit tests.

The problem was that calling `std::shared_ptr<void>::reset()` with a `void` pointer cannot possibly update the `shared_from_this` `weak_ptr`.

The solution is to store a `shd_ptr_reset` function pointer in `guarded_deleter` (similar in idea to the stored function pointer for calling `delete`).

This commit still includes all debugging code, i.e. is "dirty". The code will be cleaned up after the GitHub CI is fully successful.

smart_holder fixups (#3012)
* Drop constraints on casting of std::shared_ptr

std::shared_ptrs can be shared across python and C++ by design.

* Correctly report casting error

It is important to return an empty handle.
Simply returning None, would skip the error handling in
simple_collector / unpacking_collector, although a python exception is set.
A function call would then be processed with a (wrong) None argument!

* Return None for nullptr

* Revert "Drop constraints on casting of std::shared_ptr"

This reverts commit 7cf53ae8b4.

Fix Unicode support for ostream redirects (#2982)
* Crash when printing Unicode to redirected cout
Add failing tests

* Fix Unicode crashes redirected cout

* pythonbuf::utf8_remainder check end iterator

* Remove trailing whitespace and formatting iostream

* Avoid buffer overflow if ostream redirect races
This doesn't solve the actual race, but at least it now has a much lower
probability of reading past the end of the buffer even when data races
do occur.

Fix compilation with gcc < 5 (#2956)
When the user defines _GLIBCXX_USE_CXX11_ABI=0 to force the pre-c++11 ABI, numpy.h assumes that is_trivially_copyable is available.
It is not necessarily the case. This patch uses clang's feature detection instead.
The workaround is for certain libstdc++ versions, so the test should target these particular versions.

Open question, with respect to the original code:
76a160070b/include/pybind11/pybind11.h (L1510)
To me it looks like the exact situation marked as `std::shared_ptr<Good> gp1 = not_so_good.getptr();` here: https://en.cppreference.com/w/cpp/memory/enable_shared_from_this
The comment there is: `// undefined behavior (until C++17) and std::bad_weak_ptr thrown (since C++17)`
Does the existing code have UB pre C++17?

I'll leave handling of enable_shared_from_this for later, as the need arises.

* Cosmetical change around helper functions.

* Using type_caster_base<mpty>::src_and_type directly, removing copy. Also renaming one cast to cast_const_raw_ptr, for clarity.

* Using factored-out make_constructor (PR #2798), removing duplicate code.

* Inserting additional assert to ensure a returned unique_ptr is always a new Python instance.

* Adding minor comment (change to internals needed to distinguish uninitialized/disowned in error message).

* Factoring out find_existing_python_instance().

* Moving factored-out make_constructor to test_classh_wip.cpp, restoring previous version of cast.h. This is currently the most practical approach. See PR #2798 for background.

* Copying classh type_casters from test_classh_wip.cpp UNMODIFIED, as a baseline for generalizing the code.

* Using pybind11/detail/classh_type_casters.h from test_classh_wip.cpp.

* Adding & using PYBIND11_CLASSH_TYPE_CASTERS define.

* Adding test_classh_inheritance, currently failing (passes with class_).

* Removing .clang-format before git rebase master (where the file was added).

* Bringing back .clang-format, the previous rm was a bad idea.

* Folding in modified_type_caster_generic_load_impl, just enough to pass test_class_wip. test_classh_inheritance is still failing, but with a different error: [RuntimeError: Incompatible type (as_raw_ptr_unowned).]

* Minimal changes needed to pass test_classh_inheritance.

* First pass adjusting try_implicit_casts and try_load_foreign_module_local to capture loaded_v_h, but untested and guarded with pybind11_failure("Untested"). This was done mainly to determine general feasibility. Note the TODO in pybind11.h, where type_caster_generic::local_load is currently hard-coded. test_classh_wip and test_classh_inheritance still pass, as before.

* Decoupling generic_type from type_caster_generic.

* Changes and tests covering classh_type_casters try_implicit_casts.

* Minimal test covering classh_type_casters load_impl Case 2b.

* Removing stray isinstance<T>(src): it interferes with the py::module_local feature. Adding missing #includes.

* Tests for classh py::module_local() feature.

* Pure renaming of function names in test_classh_inheritance, similar to the systematic approach used in test_class_wip. NO functional changes.

* Pure renaming of function and variable names, for better generalization when convoluting with inheritance. NO functional changes.

* Adopting systematic naming scheme from test_classh_wip. NO functional changes.

* Moving const after type name, for functions that cover a systematic scheme. NO functional changes.

* Adding smart_holder_type_caster_load::loaded_as_shared_ptr, currently bypassing smart_holder shared_ptr tracking completely, but the tests pass and are sanitizer clean.

* Removing rtti_held from smart_holder. See updated comment.

* Cleaning up loaded_as_raw_ptr_unowned, loaded_as_shared_ptr.

* Factoring out convert_type and folding into loaded_as_unique_ptr.

* Folding convert_type into lvalue_ref and rvalue_ref paths. Some smart_holder_type_caster_load cleanup.

* Using unique_ptr in local_load to replace static variable. Also adding local_load_safety_guard.

* Converting test_unique_ptr_member to using classh: fully working, ASAN, MSAN, UBSAN clean.

* Removing debugging comments (GET_STACK, GET_INT_STACK). cast.h is identical to current master again, pybind11.h only has the generic_type::initialize(..., &type_caster_generic::local_load) change.

* Purging obsolete pybind11/vptr_holder.h and associated test.

* Moving several tests to github.com/rwgk/rwgk_tbx/tree/main/pybind11_tests

a2c2f88174

These tests are from experimenting, and for demonstrating UB in pybind11 multiple inheritance handling ("first_base"), to be fixed later.

* Adding py::smart_holder support to py::class_, purging py::classh completely.

* Renaming files in include directory, creating pybind11/smart_holder.h.

* Renaming all "classh" to "smart_holder" in pybind11/detail/smart_holder_type_casters.h.

The user-facing macro is now PYBIND11_SMART_HOLDER_TYPE_CASTERS.

* Systematically renaming tests to use "class_sh" in the name.

* Renaming test_type_caster_bare_interface_demo to test_type_caster_bare_interface.

* Renaming new tests/core subdirectory to tests/pure_cpp.

* Adding new tests to CMake config, resetting CI config.

* Changing CMake file so that test_class_sh_module_local.py actually runs.

* clang-tidy fixes.

* 32-bit compatibility.

* Reusing type_caster_base make_copy_constructor, make_move_constructor with a trick.

* CMake COMPARE NATURAL is not available with older versions.

* Adding copyright notices to new header files.

* Explicitly define copy/move constructors/assignments.

* Adding new header files to tests/extra_python_package/test_files.py.

* Adding tests/pure_cpp/CMakeLists.txt.

* Making use of the new find_existing_python_instance() function factored out with PR #2822.

* Moving define PYBIND11_SMART_HOLDER_TYPE_CASTERS(T) down in the file. NO functional changes. Preparation for follow-up work (to keep that diff smaller).

* Reintroducing py::classh, this time as a simple alias for py::class_<U, py::smart_holder>.

* Replacing detail::is_smart_holder<H> in cast.h with detail::is_smart_holder_type_caster<T>.
Moving get_local_load_function_ptr, init_instance_for_type to smart_holder_type_caster_class_hooks.
Expanding static_assert in py::type::handle_of<> to accommodate smart_holder_type_casters.

* Fixing oversight.

* Adding classu alias for class_<U, std::unique_ptr<U>>.

* Giving up on idea to use legacy init_instance only if is_base_of<type_caster_generic, type_caster<T>. There are use cases in the wild that define both a custom type_caster and class_.

* Removing test_type_caster_bare_interface, which was moved to the separate PR #2834.

* Moving up is_smart_holder_type_caster, to also use in cast_is_temporary_value_reference.

* Adding smart_holder_type_casters for unique_ptr with custom deleter. SEVERE CODE DUPLICATION. This commit is to establish a baseline for consolidating the unique_ptr code.

* Unification of unique_ptr, unique_ptr_with_deleter code in smart_holder_poc.h. Leads to more fitting error messages. Enables use of unique_ptr<T, D> smart_holder_type_casters also for unique_ptr<T>.

* Copying files as-is from branch test_unique_ptr_member (PR #2672).

* Adding comment, simplifying naming, cmake addition.

* Introducing PYBIND11_USE_SMART_HOLDER_AS_DEFAULT macro (tested only undefined; there are many errors with the macro defined).

* Removing test_type_caster_bare_interface, which was moved to the separate PR #2834.

* Fixing oversight introduced with commit 95425f13d6.

* Setting record.default_holder correctly for PYBIND11_USE_SMART_HOLDER_AS_DEFAULT.

With this test_class.cpp builds and even mostly runs, except
`test_multiple_instances_with_same_pointer`, which segfaults because it is
using a `unique_ptr` holder but `smart_holder` `type_caster`.

Also adding `static_assert`s to generate build errors for such situations,
but guarding with `#if 0` to first pivot to test_factory_constructors.cpp.

* Fixing up cast.h and smart_holder.h after rebase.

* Removing detail/smart_holder_type_casters.h in separate commit.

* Commenting out const in def_buffer(... const). With this, test_buffers builds and runs with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT. Explanation why the const needs to be removed, or fix elsewhere, is still needed, but left for later.

* Adding test_class_sh_factory_constructors, reproducing test_factory_constructors failure. Using py::class_ in this commit, to be changed to py::classh for debugging.

* Removing include/pybind11/detail/smart_holder_type_casters.h from CMakeLists.txt, test_files.py (since it does not exist in this branch).

* Adding // DANGER ZONE reminders.

* Converting as many py::class_ to py::classh as possible, not breaking tests.

* Adding initimpl::construct() overloads, resulting in test_class_sh_factory_constructors feature parity for py::class_ and py::classh.

* Adding enable_if !is_smart_holder_type_caster to existing initimpl::construct(). With this test_factory_constructors.cpp builds with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT.

* Disabling shared_ptr&, shared_ptr* tests when building with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT for now, pending work on smart_holder_type_caster<shared_ptr>.

* Factoring out struct and class definitions into anonymous namespace. Preparation for building with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT.

* Simplifying from_unique_ptr(): typename D = std::default_delete<T> is not needed. Factoring out is_std_default_delete<T>() for consistentcy between ensure_compatible_rtti_uqp_del() and from_unique_ptr().

* Introducing PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS. Using it in test_smart_ptr.cpp. With this test_smart_ptr builds with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT and all but one test run successfully.

* Introducing 1. type_caster_for_class_, used in PYBIND11_MAKE_OPAQUE, and 2. default_holder_type, used in stl_bind.h.

* Using __VA_ARGS__ in PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS.

* Replacing condense_for_macro with much simpler approach.

* Softening static_assert, to only check specifically that smart_holder is not mixed with type_caster_base, and unique_ptr/shared_ptr holders are not mixed with smart_holder_type_casters.

* Adding PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS in test_class.cpp (with this all but one test succeed with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT).

* Adding remaining PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS. static_assert for "necessary conditions" for both types of default holder, static_assert for "strict conditions" guarded by new PYBIND11_STRICT_ASSERTS_CLASS_HOLDER_VS_TYPE_CASTER_MIX. All tests build & run as before with unique_ptr as the default holder, all tests build for smart_holder as the default holder, even with the strict static_assert.

* Introducing check_is_smart_holder_type_caster() function for runtime check, and reinterpreting record.default_holder as "uses_unique_ptr_holder". With this test_smart_ptr succeeds. (All 42 tests build, 35 tests succeed, 5 run but have some failures, 2 segfault.)

* Bug fix: Adding have_value() to smart_holder_type_caster_load. With this test_builtin_casters succeeds. (All 42 tests build, 36 tests succeed, 5 run but have some failures, 1 segfault.)

* Adding unowned_void_ptr_from_direct_conversion to modified_type_caster_generic_load_impl. This fixes the last remaining segfault (test_numpy_dtypes). New stats for all tests combined: 12 failed, 458 passed.

* Adding "Lazy allocation for unallocated values" (for old-style __init__) into load_value_and_holder. Deferring destruction of disowned holder until clear_instance, to remain inspectable for "uninitialized" or "disowned" detection. New stats for all tests combined: 5 failed, 465 passed.

* Changing std::shared_ptr pointer/reference to const pointer/reference. New stats for all tests combined: 4 failed, 466 passed.

* Adding return_value_policy::move to permissible policies for unique_ptr returns. New stats for all tests combined: 3 failed, 467 passed.

* Overlooked flake8 fixes.

* Manipulating failing ConstructorStats test to pass, to be able to run all tests with ASAN.

This version of the code is ASAN clean with unique_ptr or smart_holder as the default.

This change needs to be reverted after adopting the existing move-only-if-refcount-is-1
logic used by type_caster_base.

* Adding copy constructor and move constructor tracking to atyp. Preparation for a follow-up change in smart_holder_type_caster, to make this test sensitive to the changing behavior.

[skip ci]

* Removing `operator T&&() &&` from smart_holder_type_caster, for compatibility with the behavior of type_caster_base. Enables reverting 2 of 3 test manipulations applied under commit 249df7cbdb. The manipulation in test_factory_constructors.py is NOT reverted in this commit.

[skip ci]

* Fixing unfortunate editing mishap. This reverts the last remaining test manipulation in commit 249df7cbdb and makes all existing unit tests pass with smart_holder as default holder.

* GitHub CI clang-tidy fixes.

* Adding messages to terse `static_assert`s, for pre-C++17 compatibility.

* Using @pytest.mark.parametrize to run each assert separately (to see all errors, not just the first).

* Systematically removing _atyp from function names, to make the test code simpler.

* Using re.match to accommodate variable number of intermediate MvCtor.

* Also removing `operator T()` from smart_holder_type_caster, to fix gcc compilation errors. The only loss is pass_rref in test_class_sh_basic.

* Systematically replacing `detail::enable_if_t<...smart_holder...>` with `typename std::enable_if<...smart_holder...>::type`. Attempt to work around MSVC 2015 issues, to be tested via GitHub CI. The idea for this change originates from this comment: https://github.com/pybind/pybind11/issues/1616#issuecomment-444536813

* Importing re before pytest after observing a PyPy CI flake when importing pytest first.

* Copying MSVC 2015 compatibility change from branch pr2672_use_smart_holder_as_default.

* Introducing is_smart_holder_type_caster_base_tag, to keep smart_holder code more disconnected.

* Working around MSVC 2015 bug.

* Expanding comment for MSVC 2015 workaround.

* Systematically changing std::enable_if back to detail::enable_if_t, effectively reverting commit 5d4b6890a3.

* Removing unused smart_holder_type_caster_load::loaded_as_rvalue_ref (it was an oversight that it was not removed with commit 23036a45eb).

* Removing py::classu, because it does not seem useful enough.

* Reverting commit 6349531306 by un-commenting `const` in `def_buffer(...)`. To make this possible, `operator T const&` and `operator T const*` in `smart_holder_type_caster` need to be marked as `const` member functions.

* Adding construct() overloads for constructing smart_holder from alias unique_ptr, shared_ptr returns.

* Adding test_class_sh_factory_constructors.cpp to tests/CMakeLists.txt (fixes oversight, this should have been added long before).

* Compatibility with old clang versions (clang 3.6, 3.7 C++11).

* Cleaning up changes to existing unit tests.

* Systematically adding SMART_HOLDER_WIP tag. Removing minor UNTESTED tags (only the throw are not actually exercised, investing time there has a high cost but very little benefit).

* Splitting out smart_holder_type_casters again, into new detail/smart_holder_type_casters_inline_include.h.

* Splitting out smart_holder_init_inline_include.h.

* Adding additional new include files to CMakeLists.txt, tests/extra_python_package/test_files.py.

* clang-format cleanup of most smart_holder code.

* Adding source code comments in response to review.

* Simple micro-benchmark ("ubench") comparing runtime performance for several holders.

Tested using github.com/rwgk/pybind11_scons and Google-internal build system.
Sorry, no cmake support at the moment.

First results: https://docs.google.com/spreadsheets/d/1InapCYws2Gt-stmFf_Bwl33eOMo3aLE_gc9adveY7RU/edit#gid=0

* Accounting for ubench in MANIFEST.in (simply prune, for now).

* Smarter determination of call_repetitions.

[skip ci]

* Renaming is_smart_holder_type_caster_base_tag -> smart_holder_type_caster_base_tag for simplicity.

* Adding copyright notices and minor colateral cleanup.

* iwyu cleanup (comprehensive only for cast.h and smart_holder*.h files).

* Fixing `git rebase master` accident.

* Moving large `pragma warning` block from pybind11.h to detail/common.h.

* Fixing another `git rebase master` accident.

* Force the builtin module key to be the correct type.

Previously it was always going to be a std::string which converted into
unicode. Python 2 appears to want module keys to be normal str types, so
this was breaking code that expected plain string types in the
builtins.keys() data structure

* Update the unit test so it will also run on pypy

* Run pre-commit.

docs: pybind11/numpy.h does not require numpy at build time. (#2720)

This is nice enough to be mentioned explicitly in the docs.

docs: Update warning about Python 3.9.0 UB, now that 3.9.1 has been released (#2719)

Adjusting `type_caster<std::reference_wrapper<T>>` to support const/non-const propagation in `cast_op`. (#2705)

* Allow type_caster of std::reference_wrapper<T> to be the same as a native reference.

Before, both std::reference_wrapper<T> and std::reference_wrapper<const T> would
invoke cast_op<type>. This doesn't allow the type_caster<> specialization for T
to distinguish reference_wrapper types from value types.

After, the type_caster<> specialization invokes cast_op<type&>, which allows
reference_wrapper to behave in the same way as a native reference type.

* Add tests/examples for std::reference_wrapper<const T>

* Add tests which use mutable/immutable variants

This test is a chimera; it blends the pybind11 casters with a custom
pytype implementation that supports immutable and mutable calls.

In order to detect the immutable/mutable state, the cast_op needs
to propagate it, even through e.g. std::reference<const T>

Note: This is still a work in progress; some things are crashing,
which likely means that I have a refcounting bug or something else
missing.

* Add/finish tests that distinguish const& from &

Fixes the bugs in my custom python type implementation,
demonstrate test that requires const& and reference_wrapper<const T>
being treated differently from Non-const.

* Add passing a const to non-const method.

* Demonstrate non-const conversion of reference_wrapper in tests.

Apply formatting presubmit check.

* Fix build errors from presubmit checks.

* Try and fix a few more CI errors

* More CI fixes.

* More CI fixups.

* Try and get PyPy to work.

* Additional minor fixups. Getting close to CI green.

* More ci fixes?

* fix clang-tidy warnings from presubmit

* fix more clang-tidy warnings

* minor comment and consistency cleanups

* PyDECREF -> Py_DECREF

* copy/move constructors

* Resolve codereview comments

* more review comment fixes

* review comments: remove spurious &

* Make the test fail even when the static_assert is commented out.

This expands the test_freezable_type_caster a bit by:
1/ adding accessors .is_immutable and .addr to compare identity
from python.
2/ Changing the default cast_op of the type_caster<> specialization
to return a non-const value. In normal codepaths this is a reasonable
default.
3/ adding roundtrip variants to exercise the by reference, by pointer
and by reference_wrapper in all call paths.  In conjunction with 2/, this
demonstrates the failure case of the existing std::reference_wrpper conversion,
which now loses const in a similar way that happens when using the default cast_op_type<>.

* apply presubmit formatting

* Revert inclusion of test_freezable_type_caster

There's some concern that this test is a bit unwieldly because of the use
of the raw <Python.h> functions. Removing for now.

* Add a test that validates const references propagation.

This test verifies that cast_op may be used to correctly detect
const reference types when used with std::reference_wrapper.

* mend

* Review comments based changes.

1. std::add_lvalue_reference<type> -> type&
2. Simplify the test a little more; we're never returning the ConstRefCaster
type so the class_ definition can be removed.

* formatted files again.

* Move const_ref_caster test to builtin_casters

* Review comments: use cast_op and adjust some comments.

* Simplify ConstRefCasted test

I like this version better as it moves the assertion that matters
back into python.

Adjusting type_caster<std::reference_wrapper<T>> to support const/non-const propagation in cast_op. (#2705)
* Allow type_caster of std::reference_wrapper<T> to be the same as a native reference.

Before, both std::reference_wrapper<T> and std::reference_wrapper<const T> would
invoke cast_op<type>. This doesn't allow the type_caster<> specialization for T
to distinguish reference_wrapper types from value types.

After, the type_caster<> specialization invokes cast_op<type&>, which allows
reference_wrapper to behave in the same way as a native reference type.

* Add tests/examples for std::reference_wrapper<const T>

* Add tests which use mutable/immutable variants

This test is a chimera; it blends the pybind11 casters with a custom
pytype implementation that supports immutable and mutable calls.

In order to detect the immutable/mutable state, the cast_op needs
to propagate it, even through e.g. std::reference<const T>

Note: This is still a work in progress; some things are crashing,
which likely means that I have a refcounting bug or something else
missing.

* Add/finish tests that distinguish const& from &

Fixes the bugs in my custom python type implementation,
demonstrate test that requires const& and reference_wrapper<const T>
being treated differently from Non-const.

* Add passing a const to non-const method.

* Demonstrate non-const conversion of reference_wrapper in tests.

Apply formatting presubmit check.

* Fix build errors from presubmit checks.

* Try and fix a few more CI errors

* More CI fixes.

* More CI fixups.

* Try and get PyPy to work.

* Additional minor fixups. Getting close to CI green.

* More ci fixes?

* fix clang-tidy warnings from presubmit

* fix more clang-tidy warnings

* minor comment and consistency cleanups

* PyDECREF -> Py_DECREF

* copy/move constructors

* Resolve codereview comments

* more review comment fixes

* review comments: remove spurious &

* Make the test fail even when the static_assert is commented out.

This expands the test_freezable_type_caster a bit by:
1/ adding accessors .is_immutable and .addr to compare identity
from python.
2/ Changing the default cast_op of the type_caster<> specialization
to return a non-const value. In normal codepaths this is a reasonable
default.
3/ adding roundtrip variants to exercise the by reference, by pointer
and by reference_wrapper in all call paths.  In conjunction with 2/, this
demonstrates the failure case of the existing std::reference_wrpper conversion,
which now loses const in a similar way that happens when using the default cast_op_type<>.

* apply presubmit formatting

* Revert inclusion of test_freezable_type_caster

There's some concern that this test is a bit unwieldly because of the use
of the raw <Python.h> functions. Removing for now.

* Add a test that validates const references propagation.

This test verifies that cast_op may be used to correctly detect
const reference types when used with std::reference_wrapper.

* mend

* Review comments based changes.

1. std::add_lvalue_reference<type> -> type&
2. Simplify the test a little more; we're never returning the ConstRefCaster
type so the class_ definition can be removed.

* formatted files again.

* Move const_ref_caster test to builtin_casters

* Review comments: use cast_op and adjust some comments.

* Simplify ConstRefCasted test

I like this version better as it moves the assertion that matters
back into python.

Remove friend declaration of py::class_ in py::detail::generic_type (#2613)
This line had two bugs:

1. It declares `py::detail::class_` as `friend`.
2. After fixing that, we would have to change it to
   `template <typename, typename...>`

The first one was introduced ~5 years ago, when a large refactoring was
made, probably as an intermediate step during refactoring.

The second was made when `generic_type` was made to be agnostic with
respect to the order of `py::class_` template parameters.

&nbsp;

We're removing the declaration altogether, because it was never relied
on. This is what makes me think that it was an intermediate step in
refactoring that shouldn't have ended up in commit history.
